Well, it's kind of relative IMHO. First, cigars (except for the gas station gourmet variety) do not have any addatives in them. However, there are acids and tars that do build up and can have a negative effect on a human. Now, that being said, Cigarettes give you lung cancer and emphazema. Cigars can cause mouth cancer, although I doubt that this actually happens to a normal casual cigar smoker. If you don't abuse it, you should be fine. And (correct me if i'm wrong) wasn't it Groucho Marx who lived to be more than 100 years old and still smoked a cigar a day?

Oh, and the FDA is a load of Bullsh*t anyways.
